A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

One of the most extraordinary films you will see this year. Take that as you want.

After playing with our expectations, this turns out to be a very different sort of film.

Story: It's very simple but honestly that is fine.
